There are things that makes a good bounty program. One of it is the rules. Rules that are not confusing. Another one is the updated weekly status report. It makes you at ease if you will see if your work has been approved or not. Regular response from the admin is another thing that makes a good bounty program. If the admin/admins carefully take response from the queries of the bounty hunters. And most especially and importantly that makes a good bounty is the payout. The propose stakes, tokens before and until the end of the program.
